3 Claims. '(Cl. 156-17) This invention relates to improvements in bowed to permit the links when extended to lie Venetian blinds, and the principal object of the in substantial alignment. invention is to provide anovel form of articulated In assembly, the links are connected to the metal tape for uniting tlle elements of the blind. slats as illustrated in Fig. 1, with the ends 9a The invention further resides in certain novel of the links 9 at the inner side of the tape so 5 structural details and arrangements hereinafter that when the slats are moved together, the tape set forth and illustrated in the attached. drawmay fold inwardly between the slats, as illusing, in which: trated. Itiw'ill be noted by reference to Fig. 6

Figure 1 is a fragmentary view in perspective of that when the links are fully extended, the ends ,a Venetian blind equipped with a metallic tape 9a 'of the links 9' by engaging the inner faces of 10 made in accordance with my invention; the links 8 retain the links in a slightly angular Figs. 2 and 3 are detached views in perspective relation so that when the adjo i Slots are of elements of the. blind; i brought together, the links will positively fold Figs. 4 and 5 are detached views inperspective inwardly, andthere is no tendency for the links of elements of the tape,'and to remain in the extended position. The links Fig. 6 is a fragmentaryend view showing the are prevented from folding w r y as P tape in both the extended and folded conditions. viously set forth. In the fully folded position, With reference to the drawing, the slats of the links lie substantially fiat between the slats the Venetian blind are indicated by the reference and against the faces of the extension P a 2 So numeral I. In the present embodiment, each that the slats are permitted to lie close together of the slats is provided at its ends with projecting in ce to-faoe' relation.

It Will be noted that the links of Which of a series of links pivotally connected together the metal pe is formed may readily be formed 5 and to the slats I through the medium or the by s p o e a d the operation f extension plates 2. The links comprise two forms assembly. is both relatively ine p ns ve and designated respectively 8 and 9. The links 8 p are bifurcated at one end, and the bifurcations in I a assembly are turned over to form eyes 10, In 1. A metal articulated tape for Venetian blinds 40 embracing the respective pintles I of the exand e like comprising two Sets f lin arranged tension plates 2. The links 9 at one end are in end-to-end relation with the links of one set formed with a central projection which in asnating with the links of the other set, one end sembly is formed into an eye II also embracing of each of Said links being formed for p v ta the pintles I intermediate the eyes II), III of the connection directly with the slats of the blind and links 8. The other end of the link 9 is provided the opposite ends of the links being formed for with two apertures l2 and I3 providing therepivotal connection to each other, and means at between a pintle M which in assembly is emthe latter ends of the links forrestrictingto one braced by an eye l5 formed at the adjoining ends direction only the folding movement of the links of the links 8.

In a Venetian blind, the combination with the sides of the adjoining links 8 and thereby a plurality of slats, of an articulated tape conform stops limiting the relative movement of the necting said slats and comprising between each links about the pintles l4. Preferably the aperadjacent pair of slatsa pair of rigid links hinged tured ends of the links 9, are slightly offset or together at one end and hingedly connected at their opposite ends to the respective slats, said links being adapted to fold inwardly between the slats when the latter are brought together, and means for preventing folding of said links in the opposite direction. 7

3. In a Venetian blind, the combination with a plurality of slats, of an articulated tape connecting said slats and comprising between each adjacentpairoislatsapairoilinkshingedtogether and adapted to fold inwardly between the slats when the latter are brought together, apertures in one of said links forming therebetween a. pintle pin, and an extension on the other of said links embracing said pintle, the extremity of said apertured link when the links are extended engaging the inner face of the other link and preventing outward folding of said links when the slats are brought together.
